The Cisco UCS S3260 Storage Server is a modular storage server with dual M5 server nodes and is optimized for large datasets used in environments such as big data, cloud, object storage, video surveillance, and content delivery. The UCS S3260 server helps you achieve the highest levels of data availability and performance. With dual-node capability that is based on the 2nd Gen Intel® Xeon® Scalable processors, the server features up to 1080 TB of local storage in a compact 4-Rack-Unit (4RU) form factor. The drives can be configured with enterprise-class Redundant Array of Independent Disks (RAID) redundancy or with a pass-through Host Bus Adapter (HBA) controller. Network connectivity is provided up to 100G Cisco VIC or third-party adapters, with expanded unified I/O capabilities for data migration between Network-Attached Storage (NAS) and SAN environments. This storage-optimized server comfortably fits in a standard 32-inch-depth rack, such as the Cisco® R42610 Rack.Â
The Cisco UCS S3260 chassis is a modular architecture consisting of the following modules: (1) Base Chassis: contains eight redundant, hot-pluggable fans, and a rail kit. (2) Server Node: one or two UCS-S3260 M5 server nodes. â– Each S3260 M5 server node has up to two 2nd Generation Intel® Xeon® Scalable CPUs, up to 14, 2933-MHz DDR4 DIMM or DC Persistent Memory (PMem) memory slots (with One slot per CPU for App Direct Mode and 2 per CPU for Memory mode), a dual-chip passthrough controller or a dual-chip RAID controller with dual 2 GB cache and up to two 7 mm NVMe SSDs. (3) System I/O Controller (SIOC): one or two SIOCs with choice of:Â
â– Onboard Cisco UCS Virtual Interface Card 1300 platform and 2 x 40-Gbps Quad Small Form-factor Pluggable (QSFP) ports (160 Gbps of throughput), or
 ■PCIe slot based with choice of Cisco UCS VIC 1455 Quad Port 10/25G, Cisco UCS VIC 1495 Dual Port 100G, or third-party Ethernet and FC Adapters. (4) Memory:Â
â– The M5 server node accommodates seven DIMM slots per CPU. Each slot allows 16-, 32-, 64-, or 128-GB DIMM capacities.Â
■There is one Intel® Optane™ Persistent Memory (PMem) ready slot per CPU that also allows 256-GB or 512-GB PMem capacities.
 ■PMem Mode options: — App direct mode: All seven DIMM slots per CPU can be populated with DIMMs, or one PMem per CPU1 can be populated in slot A2 and one PMem for CPU2 can be populated in slot G2, with the remaining six slots per CPU being populated with DIMMs. — Memory Mode: All seven DIMM slots per CPU can be populated with DIMMs, or two PMem per CPU1 can be populated in slot C1 & F1 and two PMem for CPU2 can be populated in slot J1&M1, A2&G2 blank with the remaining slots per CPU being populated with DIMMs. (Note: Only 256 GB is qualified for Memory Mode)
